Explanation / Answer

a )

finding the electric field due to given Aq,Bq,Cq charges

here A = 3 , B = 2 , C = 7

for the charge Aq

E = k X e X 3 X q / a2

at the angle zero degrees along x-axis

for the charge Bq

E = k X e X 2 X q / ( 2 a2 )

at the angle 45 degrees

for the angle Cq

E = k X e X 7 X q / a2

at the angle 90 degrees

now the sum of these three charge of the electric field

E = k X e X 3 X q / a2 + k X e X 2 X q / ( 2 a2 ) + k X e X 7 X q / a2

E = 59 degrees

b )

the total charge of electric force q is

F = E X q

= ( k X e X 3 X q / a2 + k X e X 2 X q / ( 2 a2 ) + k X e X 7 X q / a2 ) X q

F = ( k X qe X 3 X q / a2 + k X qe X 2 X q / ( 2 a2 ) + k X qe X 7 X q / a2 )
